Scientists in China discovered that ancient humans were making surprisingly advanced stone tools during a harsh ice age 146,000 years ago. The tools, created by Homo juluensis, show careful planning and complex thinking rather than simple stone-chipping. Researchers dated the site using tiny calcite crystals inside animal bones, revealing the tools are much older than expected. The discovery challenges the idea that human creativity only thrives in easy, prosperous times.

Archaeologists working at an ancient site in central China have uncovered evidence that early humans may have become more inventive while living through a brutal ice age. The discovery comes from the Lingjing archaeological site, where researchers have spent more than 10 years excavating animal bones and sophisticated stone tools linked to an extinct human relative called Homo juluensis.

A new study found that the site dates back about 146,000 years, placing it squarely within a cold glacial period rather than a warmer era as scientists once believed. The findings challenge the long-standing idea that creativity and technological advances mainly developed during times of environmental stability and abundance.
